I understand to be a martyr one must die with the love of both the Prophet (S) and the Ahlul Bayt (AS). So with the situation in Palestine, would one who dies there be considered a martyr if they did not die with the love of Ahlul Bayt (AS)?
Allah (SWT) Knows what is in the heart of every one and we are not entitled to judge the intentions of people. Allah Knows why there were killed and what was in their hearts when they were defending their homes and families. We read in the Hadeeths that a person who dies while defending his family or land will get the reward of Shaheed.
'Our responsibility as followers of Ahlul Bayt (AS) is to support the oppressed against the oppressors as Ameerul Mo'mineen Ali (AS) ordered us: Be against the oppressor and with the oppressed.
Wassalam.
